Note: 
No responses to the service $20 request from any node (because programming mode was active). This
eliminates any link errors due to unsynchronized switching from high speed mode. At this point all nodes
perform a software reset.
Note: 
After issuing the ReturnToNormalMode ($20) service in this step, the tester suspends the TesterPresent
($3E) service, and must wait 1 s before proceeding to the next step to allow sufficient time for all the nodes to
reset and syncronize normal communication.
Optionally steps may follow the ReturnToNormalMode ($20) request message to finalize the programming of
the ECU. Those steps are controlled by the utility file of the ECU. The following shows a generic example of a
service $3B write performed as part 2 of the utility file process.
Wake-up link.

Perform a high voltage wake-up on LS-CAN.

•
Wait 500 ms after wake-up, then transmit a service $10 request message (level $04), that forces Gateway
ECUs to perform a wake-up on the sub-nets to which they are connected.
